I corrected my note -- its LiFePo4 - Lithium Iron Phosphate... I'm on my 2nd, the 1st lasted 4 1/2 years, running the new one now..
I have had good luck with it. Stuff about it... if you let it sit in bike for around 8 weeks, parasitic losses will be a concern... a quick ride will keep it up.
For the season, I am never that long between rides, so it doesnt matter.
The only maintenance concern is it doesnt like to sit cold, so the recommended thing is to bring it in the house.
The static charged voltage is 13.3v so to start in November its 13.3 and when I check it in spring... its 13.3, no discharge with no load...
Some here say you need a charger... I debate that, its not my experience.... ---maybe if you leave it on bike, that may be true...
> For you, being in Arizona, you may be hosed no matter what with the hot climate, and typical Honda charging systems just suck anyway...
